MORTISE-MRKING DEVICE.

Speciication of Letters Patent.

To all whom 'it may concern:

Be it known that I, CHARLES S'rUR'rz, a citizen of the United States,residing at Arkansas City, in the county of Cowley and State of Kansas,have invented certain new and useful Improvements in Mortise-MarkingDevices, of specification.

'llie present invention is in the nature of u novel device for usebycarpenters or the like wheiiinarking a door or similar member previousto inortising the same to receive a lock, and the primary jobject of theinvention is the provision ot' a marking device ot' this character whichwill enabler-a carpenter to mark and mortise a number of doors in but asmall fraction of the time usually required tor that purpose. i

vTo this end the invention resides essentially iii the provision ot' anovel form of marking device which can be placedv against a lock of anyordinary size or description and quickly adjusted for the same, and thensubsequently applied to any number of doors or like members so as tomark the saine without further reference to the lock or without thenecessity of taking accurate measurements.

For a. full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details ot construction and the meansfor effecting the result,,reference is to be had to the followingdescription and. accompanying drawings, in which:

Figure l is a perspective view ot a marking device embodying theinvention; Fig. 2 is a longitudinal sectional view through the saine;Fig. '3 is a horizontal sectional vview on the line l-3 of Fig. 1, theswinging leaf being shown as swung into alinement with the side plate;`Fig. 4 is a detail perspective view of the marking plate.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views ot the drawings by the sainereference characters.

Referring to the drawing, the numeral 1 designates the stock which hasan elongated formation and is designed to be applied to the edge of thedoor when marking the saine. This stock may be of auydcsired formation,and in the present instance is shown as comprising a wooden body portionl having a metallic sheathing l" applied to one side thereof, the edgesof thc sheathing being extended over the longitudinal edgesv ot' the.longitudinal slots 3. which the following is a'I ,ing plates 4 areclamped securely wooden body portion. Ainarking point.

projects outwardly from the central portion of that face of the stockhav' lg the'inetallie sheathing applied thereto, aiill the two endportions of the stockl are formed with the Slidably mounted upon eachend of the stock on opposite sides o the central marking peint 2 are themarking plates 4 which are provided with the marking points 5 and areformed with the stems 6 which pass through the respective slots'B andare slidably mounted therein, the extremities of the stems beingthreadedfor engagement with the thumb nuts 7. \Vhen these thumb nuts Tare tightened the marktion, while when the said thumb nuts are loosenedthe marking plates can be moved toward or away from the central markingpoint 2 so that the marking points 5 thcncon will be properly positionedfor the particuv lar lock in question. These marking oints are'designedto be impressed in the e ge of the door so as to designate the centersof the openings to be bored therein in the usual manner with a brace orbit. As shown on the drawing, each of the marking plates 4 is alsoforinedwith a stop 8 which operates in the corresponding slot 3 andserves the double function of holding the marking platesI againstrotation about the stems 6 as a center, and also of limiting thelongitudinal sliding movement of the marking plates.

Extending transversely through the stock l is a pair 'of openings 9within which the rods 10 are slidably mounted, set screws 11' beingprovided for locking the rods in an adjusted position and holding themagainst movement. Both the set screws 11 and the thuinbeniits arepreferably knurled so as to admit of a firm `grip being obtained theron, and also provided with a kei-f so thatthey can be engaged by a screwdriver when it is desired to set them tightly in posit-ion. Theextremities ot' the rods 10 project upon one side of the stock wherethey are reduced and 'threaded as indicated aty 10, the said threadedends of the rods being received within a pair ot' longitudinal slots 12iii a side plate 125 which is arranged at right angles to the stock andis designed to fit against one side ot' the door. fitted upon thethreaded ends l0n ot the rods l() and the edges of the slots 12 aredesigned Nuts 14 are to be clamped between the nuts and the shouldersat. the terminations of thc reduced ends of the rods. It will thus beapparent that by loosening the set screws 11, the side plate 13 can bemoved laterally toward or away from the stock, while when the nuts 14are loosened the side plate can be moved longitudinally. Aswinging leaf15 is hinged to the edge of the plate 13 so as to be either swung intoalinement therewith or rear- Wardly against the same. This swinging leafis ptrovided with 'the longitudinal slots 16 having the slides 17mounted therein, each of the said slides being formed with a mark-'ingpoint 18 and with a thumbnut 19 b means of which it can be clampedin an a justed position.

- points 18 is designed to designate the center of,y the opening to bebored for the knob,

while the opposite marking point is designed to designate the center ofthe opening to be bored for the key-hole. It will thus be obvi- .ousthatafter the device has once been properly adjusted for an particular lock,it can be successively app ied to any number of doors and the said doorsproperly mortised without the necessityof making further reference tothe lock.

In applying the device, the stock 1 is first.

, placed against the edge of the door and fso lightly tapped to causethe marking points thereon to leave an impression, the swinging zleaf-15 being moved rearwardly against the side `plate 13 so that themarking points 18 thereon will not scratch or otherwise mar the race ofthe door. However, after the stock One of these marking' has beenpressed against the edge of the door so that the marking points thereonhave left an impression, the swinging leaf 15 is swung outwardly intoalinement with the side late 13 and the marking points 18 carried tereby pressed against the side of the. door so as to leave theirimpression thereon.

Having thus described the invention, what is claimed as new is: 1

1. In a device of the character described, the combination of a stockadapted to bc appliedto the edge 'of a door, a marking point upon thestock, marking plates slidably mounted upon the stock so as to beadjustable with respect to the marking point thereon, marking pointsupon the said plates, a side plate'carried by the stock, 'and markingmeans carried by the side plate.

2. In a device of the character described the combinationof a stockadapted -to be applied to a door, a. mai-kin point upon the stock,marking plates slidab mounted upon the stock so as tobe adjusta le withrespect to the marking point thereon, markin points upon said plates, aside plate carrie by the stock, a' hinged leaf mounted upon the edge ofsaid side plate and marking means car ried by said hinged leaf.

Intestimony whereof I aflix my signature in presence of two Witnesses.
